Craneflies are often overlooked by trout anglers as a food source. Craneflies, both in their larval form and their adult form, can be very abundant. On our local waters I have had tremendous luck the past several seasons fishing both the larva and the adults. This adult pattern came about after watching two large rainbows fight over an cranefly that was skittering down a riffle on our local tailwater. I tied up a couple of these and caught several fish on the next outing. On this video I used 210 UTC thread because my bench was such a mess that I couldn't find my bobbin with white 120 UTC thread. It was a bit too bulky at the front of the fly. Use 140 denier.
